Family members are notoriously bad at buying each other clothes – if it’s not a hideous knitted jumper from gran, then it’s a terrible pair of socks from your uncle. But one mum has made the ultimate blunder in clothes-gifting, by buying her daughter a VERY naughty T-shirt indeed.

At first glance, this Vivienne Westwood T-shirt looks totally innocent – just a white shirt with a snazzy gold pattern. On closer inspection, however, the true image is revealed.

Yep. It’s a bunch of people, doing a bunch of rude… stuff. In other words, it’s a mass orgy. According to Katie – the lucky recipient of the T-shirt – her mum innocently bought her the garment as she simply like the gold detailing and the Vivienne Westwood logo on the front.

Katie, however reckons that her mum knew all along what she was playing at…

“She’s finding it hilarious but is just as confused as I am with why it’s getting so much attention. I think she secretly knew and was just trying to wind me up but every time she looks at the shirt she just laughs hysterically.”

The tweet has gone viral with over 5,000 shares and 8,000 likes, and people are very much enjoying Katie’s mum’s oversight.

@druggedondolans KATIE I literally keep coming back to this tweet and laugh every time
